WebIn cryptography, DES-X (or DESX) is a variant on the DES (Data Encryption Standard) symmetric-key block cipher intended to increase the complexity of a brute-force attack. The technique used to increase the complexity is called key whitening . The original DES algorithm was specified in 1976 with a 56-bit key size: 2 56 possibilities for the ... Web概要.

WebThe most common form of key whitening is xor-encrypt-xor -- using a simple XOR before the first round and after the last round of encryption . The first block cipher to use a form of key whitening is DES-X, which simply uses two extra 64-bit keys for whitening, beyond the normal 56-bit key of DES. This is intended to increase the complexity of ...
